Update disasm snapshots for built-in disassemblers

Format differences from capstone:
- movz/movn shown instead of mov alias
- Immediates in hex (#0x7 vs #7)
- Branch targets as relative decimal (+8 vs #0x10)
- Condition on mnemonic (bne vs b.ne)
- ldr/str with explicit #0 offset instead of ldur/stur
- 32-bit ops use mnemonic suffix (addw) instead of w-prefix registers
- Embedded data bytes show as "unknown" instead of fake instructions
